Method for producing a three-dimensional preform from reinforcing fibers

A method for producing a three-dimensional preform from reinforcing fibers for producing a component from a fiber-reinforced plastic comprises the steps of introducing at least one layer of fibers having a binder into a draping mold, forming the at least one layer of fibers by at least one forming element which is displaceable along the draping mold, applying an airtight film to the at least one layer of fibers during or directly after the forming, creating a negative pressure in the intermediate space between the airtight film and the draping mold, activating the binder and removing the negative pressure after curing of the binder.

A method for preparing a part using a rigid tool surface having a shape. The method includes applying a breather sheet comprising gas-permeable material over the rigid tool surface. A vacuum bag is applied over the breather sheet, and a vacuum pressure is applied underneath the vacuum bag to conform the breather sheet and the vacuum bag to the shape of the rigid tool surface. A resin pre-impregnated ply is applied over the vacuum bag, and the part is positioned over the ply.

METHOD OF MANUFACTURING ELASTOMER ARTICLES HAVING EMBEDDED ELECTRONICS

A method of manufacturing a medical component includes molding a first member of the medical component from an elastomeric material. The first member includes a first end defined by a closed base wall, an opposing second end which is an open end, a sidewall extending between the first and second ends, and an internal recess to receive at least one electronic device. The method further includes positioning the electronic device within the recess of the first member to form an assembly, such that the electronic device is received in an inverted open cavity defined by the sidewall. The method further includes applying a protective film on the second end of the first member, such that the protective film covers an exposed surface of the electronic device. In addition, the method includes overmolding the assembly with the elastomeric material to form the medical component having the electronic device embedded therein.
